When your urges comes to call you need to say "No!". Why? Because you know the consequences of that move. The "Guilty" move. Take a step back and listen to yourself. Why are you doing this? Maybe there's a desire of attention, intimacy, excitement, or it's just plane loneliness. Why not work on your own relationship, especially if you are committed to one right now! Obviously, you were connected to the one you are with right now at an initial point in time. Why look elsewhere and dream about others you could be with. Is this Love or Lust?
Keep the love and the intimacy will come by being a proactive caring person. When the love you have is in your hands, yet has possibly just gone sour, you need to pick it back up. If you want to cheat on your partner, why not just leave and conclude it then be free to do as you wish. Life is full of decisions and consequences. YOU KNOW THAT! Unfaithfulness is not the answer. If you want to run away from a situation, conclude it like you mean it and stand up for who you are in your righteous mind. If you just want out for no reason, that's not true. There is always a reason. Whether your ego is too big or your pride is blinding you from a relationship that could possibly to "soul mate" connection. Getting a short term solution will only gain a long term problem in life. It all comes back to the saying, "You can run, but you can't hide." Really the "running" is from yourself and the "hiding" is from the Universe or Karma.
When life brings these negative or unwanted urges, yes even though you may have a desire for them, look to your present moment. Who is your partner at this time? Why cause yourself more trouble? Where is a solution that you will gain from and not loose from? Would you like it if someone did the same to you?
You yourself as a human being deserve love, respect, and dignity from the self. So make life fair to you and do not initiate or take revenge on anyone. Less negative tension less headaches and move on with your life if you want to, but don't make things worse than they are already. Positive thinking helps alleviate these urge stressing on your mind and you to make better decisions on a daily basis, especially when it comes to cheating on a partner you've committed to whether for now or for life. Love yourself and others will too.
